Abstract
Disclosed embodiments include hydraulic cylinder assemblies and piston assemblies for use in hydraulic cylinder assemblies. A rod is attached to a piston. The rod has first portion, a second portion with a cross-sectional area that is less than a cross-sectional area of the first portion, and a third portion positioned between the first and second portions. The third portion has a cross-sectional area that transitions between the cross-sectional area of the first portion and the cross-sectional area of the second portion. A collar is sized to fit over the rod with an internal feature that engages the third portion of the rod. A fastener holds the piston against the collar and provides a clamp force on the piston.
